Understanding TDS in water

Those days are long gone when water could be consumed directly without a second thought. The situation has completely changed now. The lakes, ponds, rivers, dams etc. are often polluted with factory and domestic waste and hence, it has become highly essential to purify water before consuming it. Apart from this, excessive usage of pesticides in agricultural fields for enhanced crop yields has also increased the pollution level in ground water.

The tap water that you receive from the municipal corporation often remains contaminated. This is due to the fact that they use outdated and inefficient methods of water purification. During its journey to your home, water often comes in contact with rusted and burst pipelines. This also leads high level of TDS in water.

What is TDS in water? Total dissolved solids (TDS) comprises of inorganic salts (principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulfates) and some small amounts of organic matter that are dissolved in water.

Effects of TDS are as follows -

1) The concentration of TDS may cause the water to be corrosive, salty or brackish taste, result in scale formation, and interfere and decrease efficiency of hot water heaters.

2) Many contain elevated levels of ions that are above the norms, such as an elevated level of nitrate, arsenic, aluminum, copper, lead, etc.


TDS in drinking water originate from natural sources, sewage, industrial waste water, and chemicals used in the water treatment process. The astounding rise in water pollution has led to the rise of water purification methods.

Boiling is water is one of the oldest water purification and is considered to be safe. Boiling water successfully eliminates pathogens but remains ineffective against suspended impurities and chemicals.

Reverse osmosis is considered to be the most efficient water purifiers of all. It is so efficient that it eliminates everything from water, minerals includes. These minerals are important to keep our body healthy.

Kent has come up with a water purifier that has all the advantages of other water purification technologies but without any of its disadvantages. It uses a combination of RO+UV+UF+TDS control to provide clean, clear, better tasting and mineral filled water.

This water purifier eliminates suspended as well as dissolved impurities. The biggest advantage of this water purifier is that you can control the TDS level in water. This ensures that you get the minerals in water without the contaminants.

Which water purifier should one rely on?

Life depends on water, and the reservoir depends on you. Water is something we rarely think about. It is common and easily accessible. It has the tendency to dissolve a substance which comes in contact with it. That includes chemicals and other pollutants. Consuming water that is made toxic with such harmful contaminants can be disastrous. Water  also contains organisms like viruses and bacteria, which can cause waterborne disease.

The tap water you receive at home is municipally disinfected, but it can get contaminated through pipes or tanks because of lack of proper distribution system  and maintenance of pipelines. Various forms of waterborne disease such as diarrhoea and polio are the most prominent among children.

According to the World Health Organization, such diseases cause about 1.8 million human fatalities annually. And it is also estimated that 88% of the disease is caused by unsafe water supply, sanitation and hygiene.

How do the Ultraviolet (UV) purifiers differ?

The market is over flooded with the domestic water purifiers that assure to provide pure drinking water. There are a number of different water purifiers with different purification methods such as Reverse Osmosis (RO), Ultra Filtration (UF) and Ultraviolet Filtration (UV).

Ultraviolet or “UV” is a type of energy found in the electromagnetic spectrum. We are exposed to them every time we step out in the sun. UV light is also responsible for causing sunburns. UV is used in a variety of applications, such as food, air and water purification.

In UV filtration, water is exposed to a short-wavelength of ultraviolet radiation that kills all the harmful organisms. UV filtration does not change the quality of the water other than killing the bacteria and virus.
Ordinary filters do not eliminate bacteria. The bacteria enter the filter and either pass through the filter or grow within the filter.

Here are some reasons why UV based water purifiers are trusted.

• UV technology has been trusted as a safe way to purify water and eliminate harmful

microorganisms.
• UV filtration provides pure water without the harmful micro-organisms and chemicals.
• These purifiers are very compact and occupy a very minimal amount of space.
• UV systems are also effective against the organism which causes gastrointestinal illness with diarrhoea.

The UV filtration process should always be the last pass after the filters to ensure that bacteria do not pass through to the drinking water.

Which Purifiers to buy?

There are many types of domestic purifiers, but the question arises is, which water purifier to buy?Kent has built the best UV water Purifier in India and ensures that no harmful chemicals leech into purified water. This technology is especially helpful when used in combination with other water purification technologies.

An example of a water purifier that that uses UV with a combination with other technologies is Kent’s Mineral RO. This water purifier uses a combination of RO+UV+UF (gravity based) + TDS control. This technology eliminates not only suspended but also dissolved impurities.
